Project Background
In March 2025, AISITE Transformer Co., LTD supplied two rectifier transformers to a steel mill in Tanzania for their EAF upgrade project. The equipment arrived at Dar es Salaam Port in May 2025. Our technical team is currently on-site guiding the final power-on commissioning.
Client Requirements
Withstand frequent load surges (30+ daily furnace startups)
High-temperature operation (equipment room reaches 48°C)
Simplified maintenance (limited local electrical expertise)
Key Milestones
| Date | Phase | Project Summary |
| 2025.3.15 | Technical alignment | Finalized foundation modification |
2025.05.08 | Equipment arrival | Container environment records normal |
2025.05.20 | Installation | Completed positioning despite crane limitations |
2025.06.18 | Commissioning | Our technicians conducting live guidance |
Current Focus (June 2025)
Pre-energization checks
✅ Insulating oil withstand voltage test (56kV)
✅ Winding resistance imbalance <0.5%
✅ Grounding system re-verification
On-site coordination
Training local electricians on HV switchgear operation
Coordinating utility company for switching impulse tests
Real-time temperature monitoring during initial loading
Progress Achievements
1.Installation adaptability
Split installation using available cranes (max unit: 8.5 tons)
Bus duct aligned with legacy system (<3mm tolerance)
2.Test data verification
No-load loss: 23.5kW (contract ≤25kW)
Sound level: 58dB (at 2m distance)
Client Statement
"The Chinese team is guiding critical power-on procedures hands-on. This knowledge transfer builds our operational confidence. All pre-tests meet contractual requirements."
In summary, at present the project is proceeding successfully. If there is any related inquiries of transformer, welcome to contatc us freely.
